    Cat d6d recoil spring cylinder leaking

    The grease is coming out the barrel on the inside as seen in the pics. Mechanic telling me I have to cut the spring and replace the cylinder and the barrel and replacing the track tensioner seals would not fix this. Is that correct or is he mistaken

    Need help identifying this dripping leak in the outer track bearing. It looks like according to the parts book I could undo these 4 bolts and replace number 3(shell)in the diagram with a new sleeve and 2 seals which have superseded that part. Am I on the right track here? I am not sure if...
